Ingredient Notes
Butter
- Butter gives Keto Lemon Cookies a tender and smooth texture without adding carbs. You may substitute coconut oil if needed.
Erythritol Powder

Lemon Juice
- Fresh lemon juice adds a tangy kick to Keto Lemon Cookies. Lime juice works as a substitute for a slightly different citrus flavor.
Eggs
